JOHN MCDERMOTT, OF WEST BERKELEY, CALIFORNIA.

OIL HEATER AND VAPORIZER.

SPECIFICATION forming part of Letters Patent N 0. 725,862, dated April21, 1903, Application filed September 27, 1902. Serial No. 125,072. (Nomodel.)

To ctZZ whont it may concern:

Be it known that I, JOHN MCDERMOTT, a citizen of the United States,residing at West Berkeley, county of Alameda, State of California, haveinvented an Improvement in Oil Heaters and Vaporizers; and Ihereby'declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to an apparatus for heating and vaporizing oil orpetroleum products for ultimate use in an oil-burner.

It consists of a mechanism for distributing the oil over a considerablesurface and means for applying the steam or other heat thereto and indetails of construction, which will be more fully explained by referenceto the accompanying drawings, in which- Figure 1 is a sectional view ofinside of heater with vertical oil-pipes between inner and outer casing.Fig. 2 is a sectional view ofinside of heater with Oil-pipe coiledaround inner casing.

It is the object of my invention to provide an apparatus for heating andvaporizing petroleum products, either the crude heavy oil or the lighterproducts thereof, by means of an apparatus within which the oil isdistributed over a considerable surface and is subjected to the heat ofthe exhaust-steam of an engine or steam otherwise supplied.

As shown in the drawings, A is an exterior case, having a steam-inlet at2 and a steamoutlet at 3. Vithin this case is a second casing, as at 4.This casing is in the present instance shown as concentric with theouter casing A, and the oil is introduced into the interior of thiscasing through a pipe 5. This pipe is here shown as passing throughastuffing-box at 6 in the bottom of the outer casing A and is screwed orotherwise fitted into the bottom of the inner casing 4. A pipe 7 extendsfrom the top of the inner casing 4 into the space Within the crown 8,which is located above the casing A, and this pipe 7 serves for theescapeof any air contained within the inner casing 4 while the oil isbeing introduced thereto. Any well-known and appropriate provision maybe made for the escape of air from the crown 8. From this inner casing 4the oil is carried down outside and between it and the outer casing A bymeans of suitably-disposed pipes 9, through which it is distributed andpassed to the outlet. I have shown these pipes arranged in two differentways. i

In Fig. 1 the pipes 9 open outwardly from the upper part of the chamber4 at various points around its circumference and extend downwardly, thelower ends discharginginto an annular chamber 10, which is located belowthe chamber 4. From this chamber 10 a pipe 11 leads outwardly and mayconnect with the burner or other receiver for the vapor and eil. Anothermanner for distributlngtlfieoil from the chamber 4 is by substituting aspiral coil9" for the pipes 9, previously described; butthe action ineither case is essentially the same, as it distributes the oil over alarge surfacewhich is exposed to the steam entering the space betweenthe chambers A and 4. The oil thus carried by either the pipes 9 or thecoil 9 will be discharged, as before stated, through the pipe 11,whether the intermediate receiver 10 be employed or omitted.

The action of the apparatus will then be as follows: The oil is suppliedby one or more pumps or by gravitation and passing through the pipe 5into the interior of the chamber 4 is first acted upon by theheatsurrounding this chamber, and its temperature is gradually raised asthe-oil rises within the chamber until it reaches the point of exit intothe surrounding pipes 9 or 9. Passing out through these pipes in reducedquantities the steam acts to stillfurther raise the temperature ofthe'oil on account of the small bodies which are subjected to the actionof the steam, and when it reaches the exit it will have beensufiiciently vaporized or heated.

'If a light oil or product is used, it will be manifest that there willbe more vaporization than if the heavy crude oil is employed. If thelatter is used, then the heat to which it is subjected will prepare itfor subsequent use in the burner to which it is conducted.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is V 1. An apparatus for heating oil, consisting ofan outer and an inner chamber, a pipe or passage by which oil isconducted into the inner chamber, an air-discharge passage connectingwith the top of said chamber, pipes connecting with the upper part ofthe chamher and adapted to convey the oil therefrom through the spaceintervening between the outer and inner chambers and steam inlet andoutlet pipes connecting with said intervening space.

2. An apparatus for heating and vaporizing oil consisting of exteriorand interior interspaced chambers, a pipe through which oil is 3. Anapparatus for the heating and Vaporizing of oil consisting of outer andinner interspaced chambers, steam inlet and outlet pipes connecting withthe space between the two chambers, a pipe through which oil is admittedinto the lower part ofthe inner chamber to rise therein whereby itstemperature is gradually raised, pipes leading from the upper part ofsaid chamber extending downwardly around the inner chamber whereby theoil is subdivided and exposed to the steam heat in smaller bodies, asupplemental chamher into which said pipes discharge and adischarge-pipe connecting with said chamber extending outwardly throughthe outer chamher.

In witness whereof I have hereunto set my hand.

JOHN MGDERMOTT.
